Note:When we convert float to int Python,the int() functiontruncates the decimal part of the number rather than rounding it to the nearest whole number. If we need rounding, we should usethe round() functionbefore converting to an integer. How to convert negative float value to int in Py...
输出ROUND_HALF_EVEN,即Round to nearest with ties going to nearest even integer方式进行进位。 我们我们要进行正确的四舍五入,我们将rounding指定为ROUND_HALF_UP即可。我们来看代码: fromdecimalimportDecimalfromdecimalimportROUND_HALF_UP,ROUND_HALF_EVENnum_1=Decimal('0.125').quantize(Decimal('0.00'),rou...
I would not suggest using the round() method to get the nearest integer, it is because the round() method uses banker's rounds, which can give an expected (for normal use) result. For example: round(2.5) # 2 round(2.5, 0) # 2.0 This post has info about that issue. To get the...

We can specify the type as int to convert a float array to an integer array. 1 2 3 4 5 6 import numpy as np X = np.array([[2.66, 4.78, -8.33], [13.99999, 0.000001, 6.5482]]) X = X.astype(int) print(X) Output: [[ 2 4 -8] [13 0 6]] Using the numpy.int_() fu...

Convert to UTC for actual delta. <TD> = <DTa> - <DTa> # Ignores jumps if they share tzinfo object. <D/DT> = <D/DT> ± <TD> # Returned datetime can fall into missing hour. <TD> = <TD> * <float> # Also `<TD> = abs(<TD>)`, `<TD> = <TD> ± <TD>`. <float> =...
One thing to notice, however, is that n.real and n.imag return an integer if n is an integer and a float if n is a float. Now that you’ve seen the basics of complex numbers, you might be wondering when you would ever need to use them. If you’re learning Python for web ...
